A team of hackers attempting to unlock Apple Inc.’s iPhone for use with GSM-based wireless carriers other than AT&T appear to have finally succeeded in their efforts, and last night began distributing their solution as a free download via several websites.
Dubbed "iUnlock," the SIM unlocking tool represents the fruits of a multi-month effort on the part of the unofficial "iPhone Dev Team" — a community of independent contributors who’ve banded together to discover and develop additional uses for the inaugural Apple handset.

Unlike commercial efforts from groups such as iPhoneSIMfree and UniquePhones, iUnlock was released Tuesday evening as a free download, and has since begun to spread rapidly across the web. Several iPhone owners and members of Apple online communities claim to have tested and verified the solution as genuine.

Where to get it? Gizmodo Mirror has it.
Info came from Apple insider.
